We are running 4.2+NFS version 3.0 from Brown University, with X-windows,
and we have been seeing the following problem:

To cause:
	Compile GNUemacs version 18.47 from scratch, with m-ibmrt.h and
	s-bsd4-2.h.
To demonstrate:
	run xemacs, and try M-x describe-function file-w<TAB>
	This will fail.  M-x describe-function file-r<TAB> succeeds.
	Emacs is not defsubr-ing file-writable-p correctly, apparently.

Workaround:
	swap the places of the DEFUN for file-writable-p and file-readable-p
	in fileio.c, and the problem goes away.

Weird!

Anybody out there have any ideas?
